The *circuits* will last more than 10 years -- things like the
processors, etc. so long as they are not abused (eg cooked
(overheated)). What wears out are things like power supplies (thermal
stress, aging filter caps, etc.), fans (bearings), disk drives
(bearings, magnatic coating). Basicically anything that normally is
warm/hot or has some kind of friction situation (anything machinical /
moving parts / bearings). Yes, things like processor chips do die, but
as often as not, the thermal grease has dried up and/or the processor
fan died and/or a case fan has died and/or the power supply went south --
any of these can take the processor out.
